Francis Fukuyama was 36 years old in 1989 when “The End of History?” made him a star. At the time, there was little in his biography to mark him as anything more than another ambitious young Cold War technocrat. He had been hired by the RAND Corporation directly out of graduate school at Harvard (where he wrote a dissertation on Soviet foreign policy under the famous political scientist Samuel Huntington) and, aside from two stints at the State Department, had remained at RAND ever since, producing geopolitical analyses whose readership did not extend beyond the national security bureaucracy.
